blastp -query YinYang.fasta -db ../../../references/blast_dbs/Pacuta_prot -out YinYang_blast_results_tab.txt -outfmt 6 -evalue 1e-25Great! Interestingly, the same gene, Pocillopora_acuta_HIv2_RNAseq.g25242.t1 is the top match for all 5 proteins I searched. Pocillopora_acuta_HIv2_TS.g24434.t1 is the second best match for all 5. That is interesting! Pocillopora_acuta_HIv2_RNAseq.g7583.t1 is also worth looking at. And Pocillopora_acuta_HIv2_TS.g21338.t1 matched all three YY1 isoforms.
